Groundwater and wells. A comprehensive guide for the design, installation and maintenance of a water well / Грунтовые воды и скважины. Полное руководство для проектирования, строительства и обслуживания скважин на воду

At the start of the twenty-first century, the demand for clean potable water is increasing at a greater rate due in part to a growing population. Additionally, societies are being forced to evaluate impacts on current and future water supplies as a result of energy and mineral development and climate changes. These evaluations include a determination of the quantity and quality of the groundwater resource.
Johnson Screens, a Weatherford company, for more than 100 years has been at the forefront in providing the water-well industry with well screens, well supplies, and—most importantly—application expertise for the evaluation, protection, and extractions of groundwater resources.
In 1936, a patent was issued to Edward E. Johnson, Inc. for a wire-wrapped screen (Figure 1.1). Since then, Johnson Screens has expanded to supply a wide variety of screens, drilling fluids, and well-treatment products that are used worldwide. In 1929, Johnson Screens began publishing the Drillers Journal, The journal became the “official” trade journal for water-well professionals. This was the beginning of a long tradition of Johnson Screens being a leader in providing educational and reference materials to the groundwater community. A copy of each issue of the Drillers Journal can be found in Appendix 1 on this book’s companion DVD. <...>
